Understanding Lead and Copper

Lead and copper are elements that can be found in drinking water, primarily due to the corrosion of older household plumbing systems. At the Jurupa Community Services District, we are committed to ensuring that your water meets all safety and quality standards.

JCSD’s Commitment to Water Safety

For decades, JCSD has monitored the levels of lead and copper in our drinking water, adhering to stringent regulations set forth by the Environmental Protection Agency (EPA) since they were established in 1991. Our proactive approach ensures that our water quality not only meets but often exceeds federal safety standards, providing you with the highest level of confidence in the water you consume every day.

How Do Lead and Copper Enter Drinking Water?

Lead can enter drinking water when plumbing materials that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The most common sources of lead in drinking water are lead pipes, faucets, and fixtures. In homes with lead pipes that connect the home to the water main, also known as lead services lines, these pipes are typically the most significant source of lead in the water. Lead pipes are more likely to be found in older cities and homes built before 1986. Among homes without lead service lines, the most common problem is with brass or chrome-plated brass faucets and plumbing with lead solder.

Health Implications and Safety Standards

The EPA has set action levels of 15 parts per billion (ppb) for lead and 1.3 parts per million (ppm) for copper to protect public health. This means utilities, such as JCSD, must ensure that water from the customer’s tap does not exceed this level in at least 90% of the homes sampled (90th percentile value). JCSD regularly monitors the water supply to ensure these levels are not exceeded and implements corrosion control measures to maintain the integrity of your water.

Volunteer Lead and Copper Monitoring Program

JCSD invited a select number of customers to participate in our voluntary Lead and Copper Monitoring Program, designed to help us continue to ensure the safety and quality of your drinking water.

Participation Steps

To participate in this free program, customers will commit to collecting samples twice, in July 2025 and January 2026.

  1. Sign Up: If you’ve been contacted by JCSD to be part of this program, please sign up by visiting www.JCSD.us/request-lead-and-copper-testing to register your participation.

  2. Sample Collection Kit Delivery: Once registered, JCSD will schedule a delivery of a sample collection kit to your home at a convenient time.

  3. Sample Collection: After receiving your kit, please collect the water sample from the kitchen faucet in the provided container after a 6 – 8 hours of no water use—ideally first thing in the morning or after returning from work.

  4. Sample Pickup: Place the sample outside your home for collection by JCSD, which will be conducted 24 hours after delivery.
